Filed April 20, 1936 INVENTOR. IV JA 06H ATTORNE Patented Aug. 24, 1937 UNITED STATES PATENT OFFICE 2,090,678 I an??? N. J. Application April 20, 1936, Serial No. 75,3ii2

3 Claims.

This invention relates to appliances for facilitating the work of hand sewing and more particularly to needle threaders.

The main object of the invention is to provide 5 a device by which any common sewing needle may be assuredly and easily threaded with suitable thread, the same being passed through the eye of the needle in a positive manner.

A further feature is in the provision of means whereby the needle to be threaded is automatically adjusted into position to receive the thread when fully entered into the device.

Another purpose is to produce a. needle threader convenient to operate, even by unskilled persons, 5 and which is small and compact, forming a useful adjunct tothe appliances usually employed by a seamstress.

These desirable objects are accomplished by the novel and practical construction and com- 20 bination of simple parts hereinafter described and illustrated in the accompanying drawing constituting an essential component of this disclosure 35 meral It), consists of a narrow casing, generally a truncated triangle, its outer, smaller end being open and its closed, opposite, or base end J2 curved semi-cylindrically by folding the thin plate constituting the side walls and provided with a perforation l3 in the extreme portion of the curved closure near its bottom.

Engaged around this curved element is a forked socket M from which projects a sheath i5, closed 45 at its outer end and having a transverse opening i6 alined with the perforation IS.

A slide [7, provided with a lip i8 to act as a handle, contains a central longitudinal slot 89 and-is freely movable between the walls of the 50 casing I 0, 'being limited by a pin 20 at either extreme movement.

Fixed rigidly in the inner end of the slide is a flexible loop. 2! of fine wire adapted to pass through the eye 22 of a needle, the loop having Q 65 opposed, slightly out bowed members connected by the bight 23 the showing of the curve in Figure 1. being exaggerated.

A common sewing needle 25 provided with a flattened head 26, containing the eye 22, is engaged, when fully entered into the threader, in 5 a rectangular aperture 28 formed in the solid base 29 of the circular opening to receive the needle.

In operation, the needle iszentered so that its head is seated in thesocket 28, whereby the eye 22 is alined and caused to register with the 10 opening l3 between the spaced walls of the threader. Thereafter the slide H is pressed inwardly until the pin 2c limits its movement. The loop 2! passes through the needle eye, the opening it and finally presses its bight 23 against the curved outer wall of the element 15 causing the loop to expand, as best seen in Figure 2; thereafter a thread 30 is entered throughth'e opening 16, and,

obviously also the loop 2i thus expanded.

Upon drawing-the slide outwardly, the thread 30 is drawn through the eye of the needle, completing the threading operation, whereupon the needle may be withdrawn, ready for use.

It is tobe understood that the sheath i5 may be'omitted and the loop 23 expanded by pressure, as' fromv an operators finger, thus providing means for threading a sewing machine needle,

'the operation of which will be apparent.

Although the foregoing is descriptive-of the preferred embodiment of the inventor, it will be apparent that minor changes may be made in its construction, without the exercise of invention or conflicting with the scope of the claims hereto appended. 5

Having thus described the invention, what is claimed-as new anddesired to secure by Letters Patent, is: g V

1. A needle threader comprising a thin, flat casing adapted to receive the shank of a needle 40 upright therein, means to compel the eye of the needle to aline with the space between the walls of said casing, a spring loop guided by the casing walls to pass through the needle eye, a closed sheath on said casing to expand said loop after passing through the eye to receive a thread, and

manual means for actuating said loop to cause its expansion.

2. A needle threader comprising a thin, flat casing having a needle receiving socket, a slide movable longitudinally between the casing walls, means to limit the movement of said slide, a second casing engaged with the first casing and havj ing a closed outer end and a spring 'loop'carried by said slide'to pass through the eyeof a needle, 56

through the eye of a needle entered fully into said socket, and a sheath carried by said casing presentin'g an abutment in said casing adapted to expand said loop to receive 'a. thread to be drawn through the needle eye upon pressing said slide inwardly to its limit.
